COMMERCIAL  FERTILIZERS. 

By  GEORGE  ROBERTS. 


Bulletin  No.  162,  issued  in  December,  1904,  gives  the  results  of  fertil- 
izer inspection  work  to  December  1st  of  the  fiscal  year  1904-05.  This 
report  gives  the  results  of  the  work  to  the  end  of  the  year,  June  30th. 
A  list  of  registered  dealers  and  manufacturers,  together  with  a  list  of 
their  registered  brands  and  materials,  is  given  in  Bulletin  No*.  162  and 
will  not  be  repeated  here.  One  additional  dealer,  Thomas  Lewis  of 
Sacramento,  was  admitted  to  registration  in  January  of  this  year,  but 
he  immediately  withdrew  from  such  business  as  would  be  subject  to  the 
fertilizer  law. 

The  samples  herein  reported  are  chiefly  those  taken  by  the  inspector 
on  his  second  trip  for  the  year,  made  between  January  1st  and  April 
15th,  and  covering  all  sections  of  the  State  in  which  fertilizers  are  sold. 
On  this  inspection  every  lot  of  goods  found  was  sampled  up  to  six  sam- 
ples of  a  brand.  The  number  of  samples  obtained  should  give  a  good 
idea  of  the  general  character  of  the  goods  put  out  by  the  various 
manufacturers. 

On  this  inspection  132  samples  of  registered  materials  were  taken, 
all  of  which  have  been  analyzed  and  are  herein  reported,  except  one 
sample  that  was  taken  from  a  lot  of  goods  that  had  been  previously 
sampled,  and  three  samples  that  were  set  aside  because  they  were  not 
taken  in  sufficient  quantity,  due  to  the  inability  of  the  inspector  to 
obtain  containers  of  sufficient  size  in  the  town  where  the  goods  were 
sampled. 

Since  the  last  report  was  issued  23  samples  of  registered  materials 
have  been  received  from  farmers  for  analysis. 

The  following  classification  may  be  made  of  all  samples  analyzed  for 
the  fiscal  year  ending  June  30,  1905:

As  has  been  the  experience  on  all  previous  inspections,  only  a  small 
proportion  of  the  registered  brands  and  materials  were  found  on  the 
market. 

DEFICIENCIES. 

In  the  151  analyses  of  registered  samples  reported,  the  following 
number  of  deficiencies  greater  than  allowed  by  law  occur:

ANALYSES    FOR    CONSUMERS. 

Any  user  of  fertilizers  may,  by  paying  the  fee  of  two  dollars  speci- 
fied by  Section  4  of  the  fertilizer  law,  have  a  sample  of  his  material 
analyzed.  This  fee  is  not  to  be  regarded  as  paying  the  cost  of  the 
analysis.  It  is  a  nominal  charge  made  to  prevent  the  sending  of  sam- 
ples through  curiosity,  as  is  always  the  case  when  analyses  are  made 
free  of  charge. 

The  sample  should  be  drawn  from  not  less  than  ten  packages,  if  the 
lot  is  five  tons  or  less;  if  the  lot  is  over  five  tons,  the  sample  should  be 
drawn  from  not  less  than  twenty  packages.  The  larger  the  number  of 
packages  sampled,  the  more  representative  the  sample  will  be.  The 
sample  drawn  as  specified  above  should  be  thoroughly  mixed,  great 
care  being  exercised  to  prevent  the  separation  of  coarse  and  fine  mate- 
rials. Not  less  than  one  quart  should  be  taken  from  this  sample  to  be 
sent  to  the  Station  for  analysis.  Whenever  possible  the  sampling 
should  be  done  in  the  presence  of  the  agent,  who  should  sign,  as  a  wit- 
ness, the  certificate  given  below.  If  the  sample  is  not  drawn  in  the 
presence  of  the  agent,  it  should  be  drawn  in  the  presence  of  some  other 
person,  who  should  sign  the  certificate  as  a  witness. 

Samples  for  consumers  will  be  given  preference  in  the  laboratory  and 
the  results  will  be  reported  as  soon  as  possible.  The  sample  should  be 
sent,  if  possible,  in  time  to  receive  the  report  before  the  fertilizer  is 
used,  in  order  that  recourse  may  be  had  to  the  original  packages  in  case 
of  controversy  with  the  manufacturer. 

The  form  of  certificate  given  below  should  be  used  in  sending  sam- 
ples for  analysis.  Blank  forms  will  be  furnished  upon  application. 
All  samples  should  be  marked  in  some  way  so  that  they  may  be 
identified.  Samples  should  be  sent  prepaid,  addressed  to  the  Fertilizer 
Control,  Experiment  Station,  Berkeley,  and  should  bear  the  name  and 
address  of  the  sender.  Bank  checks  and  money  orders  should  be  made 
payable  to  "The  Regents  of  the  University  of  California."  Letters, 
certificates,  and  remittances  should  not  be  enclosed  with  the  samples, 
but  mailed  separately.  When  the  report  of  analysis  is  received,  a 
tag   or    label    taken    from   one  of  the    bags    sampled    should    at    once 


COMMERCIAL   FERTILIZERS.  0 

be  sent  to  the  Station,  and  the  name  and  address  of  the  agent  from 
whom  the  goods  were  purchased  should  be  given.  Analyses  will  be 
made  only  for  those  who  purchase  fertilizers  for  their  own  use.  Any 
one  refusing  to  send  a  tag  or  label  as  specified  above  will  be  excluded 
from  further  privileges  under  the  above  provisions. 

CERTIFICATE  FOR  CONSUMER'S  ANALYSIS. 

Director  Agricultural  Experiment  Station,  University  of  California,  Berkeley,  Calif. 

This  is  to  certify  that  I  am  not  a  dealer  in,  or  agent  for  the  sale  of  any  fertilizer,  and 
that  the  fertilizer,  a  sample  of  which  I  have  sent  yon  for  analysis,  was  purchased  by 
me ,  190     ,  for  my  own  use  and  not  for  sale. 

I  further  certify  that  the  amount  purchased  was tons  and  that  the  sample 

was  drawn  from packages  and  was  thoroughly  mixed. 

Upon  receipt  of  the  analysis  from  you,  I  agree  to  furnish  you  with  a  tag  or  label 
taken  from  one  of  the  packages  sampled,  and  the  name  and  address  of  the  firm  or  agent 
of  whom  the  fertilizer  was  purchased.     I  enclose  two  dollars  analysis  fee.

VALUATION    OF    FERTILIZERS. 

The  "agricultural  value"  and  the  "commercial  value"  of  fertilizing 
materials  are  not  synonymous  terms.  The  agricultural  value  of  a  fer- 
tilizer is  determined  by  the  increase  and  quality  produced  by  it  in  the 
crop.  The  commercial  value  of  a  fertilizer  is  determined  by  the  cost 
of  the  materials  which  enter  into  its  composition.  A  fertilizing  mate- 
rial of  high  commercial  value  may  have  a  low  agricultural  value  on  a 
particular  soil  or  crop.  On  another  soil  or  crop  the  same  material  may 
have  a  high  agricultural  value. 

In  calculating  the  values  given  in  this  report  the  Experiment  Station 
does  not  undertake  to  say  what  the  retail  prices  of  fertilizers  should  be 
in  this  State.  The  values  given  are  for  the  unmixed  raw  materials 
which  enter  into  the  fertilizer,  and  do  not  take  into  account  the  cost  of 
grinding,  mixing,  bagging,  insurance,  dray  age,  agent's  commission, 
and  other  expenses  of  the  manufacturer. 

The  schedule  of  values  used  is  given  below.  They  represent,  as  nearly 
as  can  be  determined,  the  prices  at  which  fertilizing  ingredients  in  raw 
materials  of  good  quality  can  be  bought  at  retail  for  cash  at  the  ware- 
house in  our  largest  markets,  like  San  Francisco.  Quotations  were 
called  for  from  dealers,  but  they  varied  so  widely  that  it  was  very  diffi- 
cult to  arrive  at  a  schedule  of  values  that  represent  the  actual  market 
conditions. 

The  estimation  of  values  is  not  without  its  use,  even  if  the  schedule 
used  does  not  represent  the  actual  market  conditions.  In  the  first 
place,  a  comparison  of  values  calculated  upon  the  guarantee  and  the 


6  UNIVERSITY    OF    CALIFORNIA— EXPERIMENT    STATION. 

analysis  shows  whether  the  goods  have  the  commercial  value  represented 
by  the  guaranteed  analysis.  In  the  second  place,  the  calculation  of 
values  upon  different  guaranteed  analyses  enables  the  purchaser  to 
determine  which  dealer  offers  him  plant  food  at  the  lowest  price,  pro- 
vided, of  course,  that  the  materials  offered  are  of  the  same  quality. 

In  reading  the  report  of  analyses,  the  column  of  values  is  the  last 
one  to  be  considered.  The  first  things  to  consider  are  the  materials 
used  and  the  analysis  as  compared  with  the  guarantee.  From  the  very 
nature  of  the  case  the  analysis  must  differ  somewhat  from  the  guaran- 
tee, but  the  variation  should  not  be  so  great  as  to  change  the  nature  of 
the  fertilizer.  Such  a  variation  might  take  place,  and  at  the  same  time 
the  value  calculated  upon  the  guarantee  be  greater  than  the  value 
calculated  upon  the  analysis.  Suppose,  for  example,  that  a  fertilizer 
should  be  guaranteed  to  have  the  composition  indicated  by  the  first 
column  below,  and  upon  analysis  it  should  show  the  composition  indi- 
cated by  the  second  column.

According  to  the  schedule  of  values  now  in  use  these  two  composi- 
tions would  have  the  same  commercial  value,  yet  they  are  essentially 
different.     Such  variations  as  the  above  are  sometimes  met  with.

$1.44  X  20  =$28.80  per  ton. 

MECHANICAL    CONDITION    OF    FERTILIZERS. 

The  mechanical  condition  of  fertilizers  is  an  extremely  important 
consideration.  Especially  is  this  true  of  those  materials  in  the  fertil- 
izer which  are  not  soluble  in  water.  It  may  be  laid  down  as  a  general 
principle  that  the  availability  of  a  given  insoluble  fertilizing  material 
varies  directly  with  its  fineness.  It  is  almost  needless  to  say,  for  exam- 
ple, that  bone  meal  and  tankage  are  much  more  effective  when  finely 
ground.  For  this  reason,  in  these  reports  the  fineness  of  these  materials 
is  given.  Fineness  is  really  a  better  test  of  their  availability  than  the 
chemical  tests  of  solution  in  various  solvents.  Fineness  and  evenness  of 
distribution  have  more  to  do  with  the  efficiency  of  a  fertilizer  than  is 
generally  supposed.  The  very  object  sought  in  using  water-soluble 
phosphoric  acid  and  potash  is  fineness  of  division  and  evenness  of 
distribution  by  solution,  for  both  of  these  materials  soon  become 
insoluble  by  fixation  in  the  soil,  but  in  an  extremely  finely  divided  and 
to ell-distributed  condition,  provided  they  were  put  in  solution  by 
sufficient  rain  or  irrigation. 

Fertilizers  in  poor  mechanical  condition  will  not  remain  well  mixed. 
For  example,  if  sulfate  of  potash,  which  is  a  heavy  and  finely  ground 
material,  is  mixed  with  coarse  dry  material,  the  inevitable  result  is 
unmixing  on  handling.  The  same  is  true  for  any  mixture  of  fine  and 
coarse  materials.  Figures  1,  2,  and  3  (one  third  natural  size)  forcibly 
illustrate  this  point.  The  sample  from  which  the  photographs  for  these 
cuts  were  made  was  sent  to  the  Station  for  analysis.  Its  identity  is  known 
only  to  the  writer,  hence  this  publication  can  not  be  given  a  personal 
significance.  The  sample  was  shipped  in  a  quart  fruit-jar  which  lay  in 
a  horizontal  position  in  the  box  in  which  it  was  shipped  and  the  sample 
was  photographed  in  the  exact  condition  in  which  it  was  received. 
Fig.  1  shows  the  side  which  was  up  in  shipping,  Fig.  2  the  bottom 
side,  while  Fig.  3    shows  the  jar  in  such  a  position  as  to  show  both 


COMMERCIAL   FERTILIZERS.  9 

top  and  bottom.  Notice  how  the  fine  materials  sift  to  the  bottom.  If 
this  is  true  for  a  jar  of  material  which  was  but  a  day  on  the  road,  it 
must  also  be  true  for  such  materials  when  subject  to  the  rough  handling 
of  freight  shipment.  Many  variations  from  guarantee  are  no  doubt  to 
be  accounted  for  in  this  way. 

An  examination  of  mechanical  condition  is  one  that  the  farmer  can 
make  for  himself,  and  he  can  do  it  more  effectively  than  it  can  be  done 
for  him;  for  when  the  manufacturer  knows  that  his  sales  will  depend 
largely  upon  mechanical  condition,  he  will  take  no  chances.  There  is 
no  provision  in  the  law  by  which  a  manufacturer  may  be  held  respon- 
sible for  the  mechanical  condition  of  his  goods.  The  presumption  is 
that  the  farmer  will  look  to  that  matter  himself. 

The  chief  reason  for  the  existence  of  fertilizer  factories  is  the  produc- 
tion of  well-mixed  goods  of  good  mechanical  condition,  at  a  cost  lower 
than  that  for  which  the  farmer  can  mix  them.  If  this  is  not  the  chief 
reason,  then  the  farmer  had  better  buy  his  own  materials  and  mix  them 
in  such  proportions  as  his  own  experience  shows  him  are  best  suited  to 
his  needs. 

IMPORTANT. 

Caution  to  Purchasers  of  Fertilizers. 

Farmers  are  requested  not  to  purchase  fertilizers  that  are  not  labeled 
to  meet  the  requirements  of  the  law,  and  not  to  attempt  to  purchase 
them  from  any  one  but  registered  dealers  or  their  authorized  agents. 
Any  farmer  who  purchases  fertilizers  under  any  other  conditions  does 
not  deserve  the  protection  of  the  law,  and  the  manufacturer  or  dealer 
who  does  not  label  his  goods  according  to  the  full  requirements  of  the 
law  is  liable  to  prosecution  and  should  in  nowise  be  patronized  by 
farmers.  It  is  quite  liable  to  happen,  and  does  happen,  that  now  and 
then  a  manufacturer  may  miss  his  guarantee  without  intending  to  do  so, 
but  it  is  impossible  that  he  would  have  his  labels  printed  in  non-con- 
formity to  the  law  without  doing  so  either  intentionally  or  through 
gross  carelessness.  Farmers  can  render  great  assistance  in  enforcing 
the  law  by  observing  the  above  caution. 

During  the  first  two  years  of  the  operation  of  the  fertilizer  law,  some 
irregularities  in  the  matter  of  labeling  have  been  met  with,  but  in  all 
cases  the  manufacturers  and  dealers  concerned  have  protested  that  they 
were  unintentional  and  were  the  result  of  a  misunderstanding  of  the 
requirements  of  the  law.  In  most  instances  such  has  appeared  to  be 
the  case;  but  there  is  no  longer  any  reason  to  believe  that  all  concerned 
do  not  fully  understand  the  requirements  of  the  law. 


10  UNIVERSITY    OF    CALIFORNIA— EXPERIMENT    STATION. 

Every  bag  or  package  of  fertilizer  and  fertilizing  material,  whether 
a  regular  brand  or  a  special  mixture,  should  carry  a  label  or  tag  bear- 
ing the  following: 

1.  Name  and  address  of  manufacturer  and  place  of  manufacture. 

2.  Registration  number. 

3.  Name  or  brand  of  fertilizer. 

4.  Guaranteed  analysis,  giving  percentage  of 

Available  phosphoric  acid ; 

Insoluble  phosphoric  acid ; 

Total  phosphoric  acid. 

Nitrogen  in  nitrates; 

Nitrogen  in  ammonia  salts ; 

Organic  nitrogen ; 

Total  nitrogen. 

Potash. 

Or  such  of  these  ingredients  as  may  be  present. 

5.  A  statement  of  the  materials  from  which  the  above  ingredients  are  derived. 

In  case  of  bone  meal,  tankage,  and  Thomas  phosphate  powder,  a 
guarantee  of  available  phosphoric  acid  is  not  required  when  these  mate- 
rials are  not  acidulated. 

No  dealer  or  manufacturer,  except  those  who  have  certificates  of 
registration  from  the  University  of  California,  and  their  authorized 
agents,  can  legally  sell  fertilizers  in  this  State.  No  person  or  com- 
pany has  any  right  to  use  any  registration  number  except  in  connec- 
tion with  the  firm  name  to  which  the  registration  certificate  of  such 
number  has  been  issued;  and  no  person  or  company  to  whom  a  regis- 
tration number  has  been  assigned  has  any  right  to  give  any  other 
person  or  company  permission  to  use  said  registration  number,  and  any 
number  so  used  is  a  fraud.  No  agent  has  any  right  to  use  his  princi- 
pal's registration  number  in  connection  with  his  own  name. 

REPORT    OF    ANALYSES. 

The  following  tables  give  the  results  of  all  analyses  made  since  the 
publication  of  Bulletin  No.  162. 

Available  phosphoric  acid  is  not  determined  in  bone  meal,  tankage, 
and  Thomas  phosphate  powder,  unless  requested.  The  fineness  of  these 
materials  is  determined,  fine  and  medium  bone  being  separated  by  a 
sieve  of  50  meshes  to  the  inch;  tankage  by  a  25-mesh  sieve;  and  Thomas 
phosphate  powder  by  a  100-mesh  sieve. 

Some  fertilizers  containing  all  three  ingredients  are  rated  as  tank- 
age, because  they  are  non-acidulated  tankage  products  with  potash  salts 
added,  and  do  not  carry  a  guarantee  of  available  phosphoric  acid. 

Nitrogen  in  ammonia  salts  will,  in  some  cases,  be  found  reported 
when  nitrogen  in  this  form  is  not  guaranteed.  In  some  of  such  cases  this 
form  of  nitrogen  is  produced  by  conversion  of  organic  nitrogen  during 
process  of  manufacture,  and  is  not  to  be  considered  a  deviation  from 


COMMERCIAL   FERTILIZERS.  11 

guarantee  of  materials  used.  This  form  is  not  reported  separately  when 
less  than  0.20  per  cent,  unless  it  has  been  guaranteed,  but  is  included 
in  the  total.  Guanos  carry  more  or  less  nitrogen  in  nitrates  and 
ammonia  salts,  and  when  any  appreciable  quantity  of  guano  is  used  the 
manufacturer  should  take  into  account  the  fact  that  some  nitrogen  will 
show  as  nitrates  and  ammonia  salts.  The  failure  to  take  this  into 
consideration  may  perhaps  account  for  the  appearance  of  these  forms 
of  nitrogen  in  some  samples  in  which  only  organic  nitrogen  was  guar- 
anteed. 

The  percentage  of  chlorin  is  given  when  it  exceeds  0.50  per  cent.  It 
is  a  matter  of  only  technical  interest  whether  chlorin  present  is  from 
muriate  of  potash,  kainit,  or  from  common  salt  that  may  be  in  some  of 
the  materials  used.  If  a  manufacturer  uses  sulfate  of  potash  and  uses 
a  tankage  with  it  containing  a  large  amount  of  chlorin,  from  a  practical 
standpoint  he  has  lowered  the  grade  of  his  fertilizer  just  as  much  as  if 
he  had  used  muriate  of  potash  instead  of  sulfate  of  potash.  Chlorin 
from  all  other  sources  is  as  objectionable  as  from  muriate  of  potash. 
However,  if  muriate  of  potash  is  found  when  sulfate  is  guaranteed,  the 
fact  will  be  published. 

The  following  abbreviations  are  used  in  the  tables:  Bl=blood;  Bn= 
bone;  Fs=fish;  G=guano;  Super=superphosphate;  T= tankage. 

Guarantees  are  entered  in  italics.  Deficiencies  greater  than  allowed 
by  law  are  entered  in  bold  type.

CALIFORNIA  FERTILIZER  LAW. 


CHAPTER  CCXXV. — An  act  to  regulate  the  sale  of  commercial  fertil- 
izers or  materials  used  for  manurial  purposes,  and  to  provide  penalties 
for  the  infraction  thereof,  and  means  for  the  enforcement  of  the  act. 

[Approved  March  20,  1903.] 

The  People  of  the  State  of  California,  represented  in  Senate  and  Assem- 
bly, do  enact  as  follows: 

Section  1.  Every  lot,  parcel,  or  package  of  commercial  fertilizers 
or  materials  to  be  used  for  manurial  purposes  (excepting  the  dung  of 
domestic  animals),  sold,  offered  or  exposed  for  sale,  within  this  State, 
shall  be  accompanied  by  a  plainly  printed  label,  stating  the  name, 
brand,  and  trade  mark,  if  any  there  be,  under  which  the  fertilizer  is 
sold,  the  name  and  address  of  the  manufacturer,  importer,  or  dealer, 
the  place  of  manufacture,  and  a  chemical  analysis,  stating  the  percent- 
ages claimed  to  be  therein;  of  nitrogen,  specifying  the  form  or  forms 
in  which  it  is  present;  of  phosphoric  acid,  available  and  insoluble;  and 
of  potash,  soluble  in  distilled  water,  and  the  materials  from  which  all 
of  said  constituents  are  derived.  All  analyses  are  to  be  made  according 
to  the  methods  agreed  upon  by  the  American  Association  of  Official 
Agricultural    Chemists.     In  the   case   of  those    fertilizers,  the    selling 


COMMERCIAL    FERTILIZERS.  27 

price  of  which  is  less  than  eight  dollars  ($8)  per  ton,  said  label  need 
only  give  a  correct  general  statement  of  the  nature  and  composition  of 
the  fertilizer  it  accompanies. 

Sec  2.  No  person  shall  sell,  offer  or  expose  for  sale  in  this  State, 
any  pulverized  leather,  hair,  ground  hoofs,  horns,  or  wool  waste,  raw, 
steamed,  roasted,  or  in  any  form  as  a  fertilizer,  or  as  an  ingredient  of  a 
fertilizer  or  manure,  without  an  explicit  statement  of  the  fact;  said 
statement  to  be  conspicuously  affixed  to  every  package  of  such  fertil- 
izer or  manure,  and  to  accompany  and  go  with  every  lot,  parcel,  or 
package  of  the  same. 

Sec  3.  The  manufacturer,  importer,  agent  of,  or  dealer  in  any  com- 
mercial fertilizers,  or  materials  used  for  manurial  purposes,  the  selling 
price  of  which  to  the  consumer  is  eight  ($8)  dollars  or  more  per  ton, 
shall,  before  the  same  is  offered  for  sale,  obtain  a  certificate  of  registra- 
tion from  the  Secretary  of  the  Board  of  Regents  of  the  University  of 
California,  countersigned  by  the  Director  of  the  Agricultural  Experi- 
ment Station  of  the  said  University,  authorizing  the  sale  of  fertilizers 
in  this  State,  and  shall  securely  fix  to  each  lot,  parcel  or  package  of 
fertilizer  the  word  "  registered  "  with  the  number  of  registry.  The  man- 
ufacturer, importer,  agent,  or  dealer,  obtaining  such  registry,  shall  pay 
to  the  said  Secretary  the  sum  of  fifty  ($50)  dollars,  to  be  applied  as 
provided  in  section  nine  of  this  act;  such  registration  shall  expire  on 
the  thirtieth  day  of  June  of  the  fiscal  year  for  which  it  was  given; 
provided,  the  provisions  of  this  section  shall  not  apply  to  any  agent 
whose  principals  shall  have  obtained  a  certificate  of  registration  as 
herein  provided.  Every  such  manufacturer,  importer,  agent,  or  dealer, 
who  makes  or  sells,  or  offers  for  sale,  any  such  substances,  under  a 
name  or  brand,  shall  file,  on  or  before  the  first  day  of  July,  in  each  year, 
a  statement,  under  oath,  with  said  Director,  stating  such  name  or  brand, 
and  stating  the  component  parts  in  accordance  with  the  provisions  of 
section  one  of  this  act,  of  the  substances  to  be  sold,  or  offered  for  sale, 
or  manufactured  under  each  such  name  or  brand. 

Sec  4.  The  said  Director  shall  annually,  on  or  before  the  first  day 
of  September,  take  samples  in  accordance  with  the  provisions  of  section 
five  hereof  of  the  substance  made,  sold,  or  offered  for  sale,  under  every 
such  name  or  brand,  and  cause  analyses  to  be  made  thereof  in 
accordance  with  the  provisions  of  section  one  hereof,  and  said  analyses 
may  include  such  other  determinations  as  said  Director  may  at  any 
time  deem  advisable.  Dealers  in,  or  manufacturers  of  fertilizers,  must 
give  free  access  to  the  Director  of  the  Agricultural  Experiment  Station, 
or  his  duly  authorized  deputy,  to  all  the  materials  which  they  may 
place  on  the  market  for  sale  in  California.  Whenever  the  analysis 
certified  by  the  said  Director  shall  show  a  deficiency  of  not  more  than  one 
fourth  of  one  per  cent  of  nitrogen,  or  one  per  cent  of  soluble  or  avail-

distilled  water,  the  statement  of  the  manufacturer  or  importer,  as 
required  in  section  one  of  this  act,  shall  not  be  deemed  to  be  false  in 
the  meaning  of  this  act;  provided,  that  this  act  shall  not  apply  to  sales 
of  fertilizing  materials  made  to  a  registered  manufacturer  of  fertilizers, 
or  to  sales  for  export  outside  of  this  State;  provided  further,  that  the 
said  Director  of  the  Agricultural  Experiment  Station  of  the  University  of 
California  shall,  upon  the  receipt  of  a  sample  of  fertilizer,  accompanied 
with  a  nominal  fee  of  two  ($2)  dollars,  furnish  to  the  user  of  said 
commercial  fertilizer,  such  examination  or  analysis  of  the  sample  as 
will  substantially  establish  the  conformity  or  non-conformity  of  the 
said  fertilizer  to  the  guarantee  under  which  it  was  sold. 

Sec.  5.  The  Director  of  the  Agricultural  Experiment  Station  of  the 
University  of  California,  in  person  or  by  deputy,  is  hereby  authorized 
to  take  a  sample  not  exceeding  two  pounds  in  weight  for  analysis  by 
the  said  Director,  or  his  deputies,  from  any  lot,  parcel,  or  package  of 
fertilizer,  or  material,  or  mixture  of  materials  used  for  manurial  pur- 
poses, which  may  be  in  the  possession  of  any  manufacturer,  importer, 
agent  or  dealer,  but  said  sample  shall  be  drawn  in  the  presence  of 
said  party  or  parties  in  interest,  or  their  representatives.  In  lots  of 
five  tons  or  less,  samples  shall  be  drawn  from  at  least  ten  packages,  or 
if  less  than  ten  packages  are  present,  all  shall  be  sampled.  In  lots  of 
over  five  tons,  not  less  than  twenty  packages  shall  be  sampled.  The 
samples  so  drawn  shall  be  thoroughly  mixed,  and  from  it  two  equal 
samples  shall  be  drawn  and  placed  in  glass  vessels,  carefully  sealed, 
and  a  label  placed  on  each,  stating  the  name  or  brand  of  the  fertilizer 
or  material  sampled,  the  name  of  the  party  from  whose  stock  the  sam- 
ple was  drawn,  and  the  time  and  place  of  drawing;  and  said  label  shall 
also  be  signed  by  the  said  Director  or  his  deputy  making  such  inspec- 
tion, and  by  the  party  or  parties  in  interest,  or  their  representatives 
present  at  the  drawing  and  sealing  of  said  samples.  One  of  said 
duplicate  samples  shall  be  retained  by  the  party  whose  stock  was 
sampled,  and  the  other  by  the  Director  of  the  Agricultural  Experiment 
Station  of  the  University  of  California. 

Sec  6.  The  Director  of  the  Agricultural  Experiment  Station  of  the 
University  of  California  shall  publish  in  bulletin  form,  from  time  to 
time,  at  least  annually,  the  results  of  the  analysis  hereinbefore  provided, 
with  such  additional  information  as  circumstances  may  advise. 

Sec  7.  There  is  hereby  appropriated  for  the  use  of  the  Agricultural 
Experiment  Station  of  the  University  of  California  at  Berkeley,  Ala- 
meda County,  as  set  forth  in  this  act,  out  of  any  moneys  in  the  treasury 
not  otherwise  appropriated,  the  sum  of  eighteen  hundred  ($1,800) 
dollars  for  the  equipment  of  a  laboratory,  with  the  chemicals  and 
apparatus,  and  other  incidentals  necessary  to  the  successful  prosecution 
of  the  work. 


COMMERCIAL    FERTILIZERS.  29 

Sec.  8.  In  order  to  further  provide  for  the  necessary  expenses  of 
this  work,  there  shall  be  paid  by  the  manufacturer,  importer,  agent,  or 
dealer,  twenty-five  cents  for  every  ton  of  fertilizer  sold,  the  selling 
price  of  which  to  the  consumer  is  eight  ($8)  dollars  or  more  per  ton. 
A  statement  sworn  to  by  the  manufacturer,  importer,  agent,  or  dealer,

Board  of  Regents  of  the  University  of  California,  accompanied  by  the 
corresponding  amount  of  the  special  license  fee  as  above  specified; 
provided,  that  whenever  the  manufacturer  or  importer  shall  have  paid 
the  special  license  fee  herein  required,  for  any  person  acting  as  agent 
or  seller  for  such  manufacturer  or  importer,  such  agent  or  seller  shall 
not  be  required  to  pay  the  special  license  fee  named  in  this  section. 
On  receipt  of  said  special  license  fee  and  statement,  the  said  Secretary 
shall  issue  to  the  manufacturer,  importer,  agent,  or  dealer,  a  certificate 
of  compliance  with  this  section. 

Sec.  9.  All  moneys,  whether  received  from  registry  and  analytical 
fees  or  special  license  fees,  shall  be  paid  to  the  Secretary  of  the  Board
